The complete season was eventually released electronically as a package but it was already available as a whole if pre-ordered by buying the first episode in 2009. This collection is also available on a double-sided DVD directly from Telltale, with the following extras:

Purchasers of the the digital download version can get the DVD for free (only shipping and handling needs to be paid) and also received some of the episodes a little earlier than single-episode buyers.

For the PS3 version this bundled collection was the first release on the platform in the series. Episodes were not available separately and that digital download version also does not include any of the extras.
